Toultwhom it may-concern:

Be it known that J0HN' am. Cincinnati, in the county of Hamilton and.

State of Ohio, have invented certain new and useful Improvements invStation Indicators,

&c.; and I do hereby declare that the following is a full, clear, andexact description there of, which'will enable others skilled inthe artto which it appertains to make'and usethe same, reference being ha'd tothe accompanying drawings and to the letters of reference markedthereon, *whichform a part of this specification.

The nature of my invention consists in the construction and arrangementof-a stationindicator, as will be hereinafter more fully set forth.

In the annexed drawing, Figure 1 is a-front View of my improvedstation-indicator. Fig. 2 is a cross-sction of the same through the linea: a; of Fig. 1. Fig. 3 is an enlarged side View of a part of theindicator. Figs. 4, 5, and 6 are detached views of detailed parts of themechanism. Fig. 7 is a' front view of the indicator with the surroundingcase. Fig. 8 is a section through the line 3 3 Fig. 7.

A represents a back plate, to which the entire mechanism is attached. Bis an apron, upon which the names of the stations are printed, orotherwise permanently attached, at regular intervals. On one side ofeach of these names is affixed the number showing the number of milesfrom one end of the route, and at the other end of the name othernumbers, showing the number of miles to the other end of the route. Thisapron B is attached to two rollers, O O, mounted in bearings, ashereinafter described, so as to roll up and unroll the apron first inone direction and then in the other-that is to say, while the trainmoves in one direction the apron is to be turned in one direction at theproper times, and when the train returns the apron will be turned in theopposite direction. At one end each roller 0 is provided with asmooth-edged metal disk, D, of larger diameter than that of the roller,and from the center of such disk projects a journal, at, which rests ina bearing, E, attached to the plate A. Between the two bearings E E arearranged two springarms, G G, which carry at their ends small rubberblocks or. rollers b b,.-thatbearv against the peripheriesof thetwodisks D D, so as to holdthem by friction from turningyexcept ard, E,also secured to the plate A. On this hub isplaced loosely a pulley-, J,.which is is hooked on a hook, i, projecting from the side of the hub h.On the inner side of the pulley J is pivoted a pawl, m, actuated by aspring, n, which pawl is to engage with the ratchet-wheel H to rotatethe roller. In the outer side of the pulley J is inserted a screw,19,Which projects therefrom and strikes the standard E, forming a stopfor the rotation of said pulley. The tension of the spring I within thepulley can easily be regulated by taking out the screw 10, turning thepulley one or more times forward or backward, and then inserting thescrew again.

wrapped around the pulley J, so that by pulling the same the pulley willbe turned on its hub nearly one revolutioii, or until stopped by thestop 10 against the other edge of the standard E, and when the tensionis removed from the cord K, the spring I will return the pulley to itsformer position. When the pulley is thus rotated by means of the cord K,the pawl. m engages with the ratchet-Wheel H, and rotates that roller 0a certain distance, suflicient to bring the name of the next station onthe apron Bin view, and when the tension on the cord is released, andthe pulley returns, the pawl slides over the ratchet-wheel withoutturning the roller.

When the spring-pulley J has reached its normal position, the pivotedend of the pawl m, projecting beyond the pivot, comes in contact-with alug or stop, .9, on the plate A, whereby the pawl is lifted away fromthe ratchet-wheel, and the roller is only held stationary' by thefriction-roller b at the opposite end. It is, of course, understood thatthe when; .the, operating mechanism is ,-actu at ed.- At theother end ofeachroller G issecured a flange, d, and ratchet-wheel El, and fromxthe;center of said wheel projects a. journal, .a-,f which hasits bearing ina hollow hub, h, se-,, I .cured in and projecting inward'from a stand-'made-hollow,;a nd contains a coiled spring, I. One end; of this; coiledspring is fastened to; the interior of the pulley, while the otherend Kis a cord or chain, attached to ands 1so.0s9

two spring-pulleys, with their pawls and ratchet-wheels for the tworollers, operate in opposite directions, so that one cord is operatedwhen the train moves in one direction,- and the other cord while itmoves in the op posite direction.

On the inner side of each pulley J is at lever L is turned on its pivot,and when the tooth passes beyond the finger a s'pring,1?, causes thehammer 0 to strike a bell, R, as shown. The finger o is pivoted on thelever L, and held by means of a spring, 20, against a pin, w, on thelever, so that the tooth t will, when the pulley is rotated by the cord,operate the lever to sound thebell; while, when. the pulley is returnedby means of its spring, the finger turns on its pivot by the action ofthe 'tooth on it in the opposite direction. There aretwo, of theselevers, fingers, and hammers, so that whichever pulley is operated thebellwill be struck. i

The plate A, with the entire mechanism as described secured thereon, isinclosed within a case, S, having suitable glass-covered openings toexpose the name of the station, as well as the numbers on each sidethereof.

.On a railroad-train it is intended to'have one of these indicators ineach car, and the cordsoperated directly from the engine, so that' theengineer can at one time givedue notice in all the cars of the name ofthe next station the train is approaching. This invention may also beused on street-railroad cars, when names of. streets will be substitutedfor names of stations.

Having thus fully described myinvention, what I claim asnew, and desireto secure by Letters Patent, is'-- 1. The spring-pulley J, provided withprojecting tooth c, in combinationwiththe pivoted lever L, carryinghammer 0, finger v, and spring-w, substantially as and for the purposeset forth. 7

2. The combination of the curtain-rollersQ with ratchet-wheels H andstandards E, havin g stationary hubs h, provided with proj ect-v inghooks -43, the hollow pulleys J, springs I, pawls m, and stops and 8,whereby the cur; tain can be operatedin both directions,fallsubstantially as and for the purposeset forth.

In testimony that I ,claim the foregoing as my own I aflix my signatureinpresence of two witnesses. Joann. .nnnzoaj WM. B. UPPERMAN,
